Repair time varies depending on the material, design, and condition of the jewelry. After inspecting your item, we will provide you with an estimated timeframe. Please rest assured.

To maintain the beauty of your jewelry for years to come, we recommend observing the following care guidelines.

Please remove your jewelry when performing household tasks, bathing, sleeping, or engaging in sports, as exposure may cause dirt buildup, discoloration, deformation, or damage.

Be sure to remove your jewelry in high-temperature environments such as saunas, or in extremely cold conditions such as ski resorts, as it may cause burns or frostbite.

Please also remove your jewelry when entering hot springs or seawater.

After each use, gently wipe your jewelry with a soft cloth to remove oils and impurities. For storage, we recommend placing each piece individually in a pouch, case, or plastic bag to help preserve its condition over time.

Please note that gold may discolor over time, as it contains alloys such as silver and copper, and may react to environmental conditions.
